etho keeps dropping and can't restart

I am havig this trouble.  The link is physically going down on eth0
and it comes back up it does't put back up the correct route


Jan 17 21:34:48 www3 kernel: e1000e 0000:00:19.0 eth0: NIC Link is Down
 Jan 17 21:34:49 www3 named[16266]: listening on IPv4 interface eth0, 96.57.23.83#53
Jan 17 21:34:52 www3 ntpd[2822]: Deleting 27 eth0, [96.57.23.83]:123, stats:
received=949, sent=887, dropped=0, active_time=230059 secs

Jan 17 21:34:52 www3 kernel: e1000e 0000:00:19.0 eth0: NIC Link is Up 1000 Mbps Full Duplex, Flow Control: Rx/Tx
Jan 17 21:34:55 www3 ntpd[2822]: Listen normally on 30 eth0 96.57.23.83:123

I have to restart it manually

It drops the default route and I have to run /etc/init.d/net.eth0 restart

Code: [Select]
[www3 ~]# /etc/init.d/net.eth0 restart
 * Unmounting network filesystems ...                                                                         [ ok ]
 * Bringing down interface eth0
Error: ipv6: Router advertisement is disabled on device.
 * Bringing up interface eth0
 *   96.57.23.83/29 ...                                                                                       [ ok ]
 *   Adding routes
 *     default via 96.57.23.81 ...                                                                            [ ok ]
 *     96.57.23.80/29 via 96.57.23.81 dev eth0 ...                                                            [ ok ]
[www3 ~]#  * Mounting network filesystems ...                                                                 [ ok ]


First why can't it just remain up regardless of the condition of the connection.  Just stay UP
second - why can't it fetch the correct route when it does up and down?  I tis obviously not using my /etc/init.d/net.eth0 file.

This is the 3rd report (the 1st 2 not in this forum) I noticed in the past 10 days about this issue.
It might very well be related to a kernel change.

This could very well be related to https://bugzilla.kernel.org/show_bug.cgi?id=118721

Comments 9 and 10 show workarounds:

Disabling TSO seems to have fixed the problem for me. (I needed to set it after a fresh boot, *before* the interface starts bailing out continually.)

Also hit this issue - might be helpful to others, reloading the module with the parameter Node=0 (The NUMA node my NIC is on - modprobe e1000e Node=0) appears to have worked around the issue.

I suggest to try these, also to clarify if it indeed is the same problem as reported here.

Linux is simple; use Artix, or Submit Your System To Evil Malicious D(a)emons

Solves it for me too with the e1000.


No issues with a wired nic laptop with

Code: [Select]
Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8211/8411 PCI Express Gigabit Ethernet Controller (rev 15)

The problem is present with our default and LTS kernel atm.
